Sensitivity analysis in trolleybus vertical dynamics
P. Polach, M. Hajžman
pages 1011 - 1023, full text

Vertical dynamic properties of the ŠKODA 21 Tr low-floor trolleybus were investigated on an artificial test track when driving with a real vehicle and when simulating driving with a multibody model on a virtual test track. Driving on the artificial test track was aimed at determining vertical dynamic properties of the real trolleybus and on the basis of them at verifying computer trolleybus models. Time histories and extreme values of the air springs relative deflections are the monitored quantities. Due to differences of the experiments and the computer simulations results the influences of the characteristics of the spring-damper structural elements of the axles suspension and the radial characteristics of the tires used in the trolleybus multibody model on the extreme values of the monitored quantities are evaluated.
